      Boost.Utility is a collection of small, useful, and general-purpose components
      for language support.

          many of these components had variants accepted into the C++ standard
        </li>

<p>
      When the component has moved to another Boost library, Boost.Utility headers
      still lead to the appropriate headers in other libraries.
